A distinctly intricate compound fart, characterised by an extended succession of harmonious 'trump' elements in an unusual composition. Comprises of more than three individual tones, which when blended together audibly- form a piece of gaseous music from one's anal passage.

A difficult skill to master, involving the contraction and controlled blowing of the anus. Usually apparent after ingestion of pro-methane-production food stuffs, such as Protein Shakes, JRAC Food or the consumption of solid effervescent tablets.

When more than one "Sphyncphony" is played from several anii (anus, plural) , this is commonly known as an Orchestral Sphyncphony, or a fucking smelly disaster.

An unforgiving volume of odour-rich methane gas is usually a bi-product of a Sphyncphony. Volumes of gas have been recorded to fill a 5 person bedroom.

Repels all female species and may be used as a room-mate deterrent.

After a succession of farts, *Laughs* "Holy shit, that was a Sphyncphony! A LOVE IT"
